Sam and extending a mirrored lv that is using strict allocation

[Error_1]

i want to extend a mirrored lv that is using strict allocation in a vg. it has 4 pv's

are there any concerns using sam?

can sam extend a lv to a specific disk?

Hi,

SAM will extend a logical volume on a
strict allocation volume.... but it is
unlikely you have the available PE's
to be able to do this. Your best bet is
to cut an ignite tape and use this
from a system boot. To cut the ignite
tape you run this command:

HPUX11
# make_tape_recovery -x inc_entire=vg00 -I -v -a /dev/rmt/0mn

HPUX10.20
# make_recovery -ACvd /dev/rmt/0mn

Note the no-rewind device must be used.
If you need to get the ignite software
here is the link:

Hi:

If you want to extend an lvol to specific physical disk then you should use lvextend; otherwise SAM will handle the extension just fine and insure that the mirrors are handled correctly and across separate devices. It will also extend the filesystem automatically but make sure that you have a lost+found directory in that filesystem so that a .fsadm file can be written - if this a a filesystem rather than a raw volume.

By the way - several people have answered your posts and forum courtesy requires that your respond with points. This serves to indicate the usefullness of the responses and also says 'thanks' to those who have tried to assist you; it's their only payment.

Hi:

You have asked over TEN QUESTIONS in the last hour or so. I don't think from your questions that you have a problem per se. Rather I believe you are studying for or taking a test.

If that is the case, please *refrain* from this kind of activity. This Forum is not intended for that.

If I am incorrect, please accept my apologies.

Hi (again):

I see. Please accept my apologies, then.

We had an unfortunate case of a pesty test-taker some months back; hence my puzzlement.
